Abstract
We present a dynamical study of hysteresis loops of a MoS2/[Au/Co/Au] sandwich performed by surface magneto-optical Kerr effect with a field variation rate up to 1.2 MOe/s. An interpretation of dynamical effects at room temperature is proposed, using a modelization of the magnetization reversal. We discuss simulations which describe two different processes of the magnetization reversal to interpret the evolution of the hysteresis loops for several rates of variation of the magnetic field. For a first range of field variation rates lower than 180 kOe/s, the predominant mechanism seems to be wall motion and beyond 180 kOe/s, an expression for the magnetization is given, which supposes micro-domains reversal as a prevailing process. Finally, the general behaviour of the relaxation time, depending on the magnetic field, is investigated.

We discuss simulations which describe two different processes of the magnetization reversal to interpret the evolution of the hysteresis loops for several rates of variation of the magnetic field. For a first range of field variation rates lower than 180 kOe/s, the predominant mechanism seems to be wall motion and beyond 180 kOe/s, an expression for the magnetization is given, which supposes micro-domains reversal as a prevailing process. Finally, the general behaviour of the relaxation time, depending on the magnetic field, is investigated.</ce:simple-para></ce:abstract-sec></ce:abstract></head></converted-article></istex:document></istex:metadataXml><mods version="3.6"><titleInfo><title>Dynamical properties of magnetization reversal in an ultrathin AuCo film</title></titleInfo><titleInfo type="alternative" contentType="CDATA"><title>Dynamical properties of magnetization reversal in an ultrathin</title></titleInfo><name type="personal"><namePart type="given">B.</namePart><namePart type="family">Raquet</namePart><affiliation>Laboratoire de Physique des Solides, S.N.C.M.P, I.N.S.A, Complexe Scientifique de Rangueil, 31077 Toulouse, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">M.D.</namePart><namePart type="family">Ortega</namePart><affiliation>Laboratoire de Physique des Solides, S.N.C.M.P, I.N.S.A, Complexe Scientifique de Rangueil, 31077 Toulouse, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">M.</namePart><namePart type="family">Goiran</namePart><affiliation>Laboratoire de Physique des Solides, S.N.C.M.P, I.N.S.A, Complexe Scientifique de Rangueil, 31077 Toulouse, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">A.R.</namePart><namePart type="family">Fert</namePart><affiliation>Laboratoire de Physique des Solides, S.N.C.M.P, I.N.S.A, Complexe Scientifique de Rangueil, 31077 Toulouse, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">J.P.</namePart><namePart type="family">Redoules</namePart><affiliation>Laboratoire de Physique des Solides, S.N.C.M.P, I.N.S.A, Complexe Scientifique de Rangueil, 31077 Toulouse, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">R.</namePart><namePart type="family">Mamy</namePart><affiliation>Laboratoire de Physique des Solides, S.N.C.M.P, I.N.S.A, Complexe Scientifique de Rangueil, 31077 Toulouse, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">J.C.</namePart><namePart type="family">Ousset</namePart><affiliation>Corresponding author.

An interpretation of dynamical effects at room temperature is proposed, using a modelization of the magnetization reversal. We discuss simulations which describe two different processes of the magnetization reversal to interpret the evolution of the hysteresis loops for several rates of variation of the magnetic field. For a first range of field variation rates lower than 180 kOe/s, the predominant mechanism seems to be wall motion and beyond 180 kOe/s, an expression for the magnetization is given, which supposes micro-domains reversal as a prevailing process. Finally, the general behaviour of the relaxation time, depending on the magnetic field, is investigated.</abstract><note type="content">Section title: Letter to the editor</note><relatedItem type="host"><titleInfo><title>Journal of Magnetism and Magnetic Materials</title></titleInfo><titleInfo type="abbreviated"><title>MAGMA</title></titleInfo><genre type="journal">journal</genre><originInfo><dateIssued encoding="w3cdtf">19950902</dateIssued></originInfo><identifier type="ISSN">0304-8853</identifier><identifier type="PII">S0304-8853(00)X0031-5</identifier><part><date>19950902</date><detail type="volume"><number>150</number><caption>vol.</caption></detail><detail type="issue"><number>1</number><caption>no.</caption></detail><extent unit="issue pages"><start>L1</start><end>L12</end></extent><extent unit="issue pages"><start>13</start><end>136</end></extent><extent unit="pages"><start>L5</start><end>L12</end></extent></part></relatedItem><identifier type="istex">C34519D013E3F2D507EC1712767D0D78EDE7B1A5</identifier><identifier type="DOI">10.1016/0304-8853(95)00515-3</identifier><identifier type="PII">0304-8853(95)00515-3</identifier><recordInfo><recordContentSource>ELSEVIER</recordContentSource></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
