Abstract

The magnetic properties have been investigated in some Sm-Co and Er-Co amorphous alloys. The samples have been obtained by r-f sputtering on different substrates. Those on glass and silica substrates have been used for structural (X-ray diffraction) and compositional (SEM) analysis. Magnetisation process (4 K

C01	`01`		`ENG`	@0 The magnetic properties have been investigated in some Sm-Co and Er-Co amorphous alloys. The samples have been obtained by r-f sputtering on different substrates. Those on glass and silica substrates have been used for structural (X-ray diffraction) and compositional (SEM) analysis. Magnetisation process (4 K<T<300 K) and hysteresis loops at 4 K have been studied over a wide range of fields (1 Oe<H<25 kOe) by using both a classical axial extraction magnetometer and a high resolution vibrating sample magnetometer (VSM). The main results are: (i) the amorphous structure is exhibited along with an enrichment of the Co element in all the deposited alloys, (ii) heat treatment and composition affect the shape of hysteresis loops, (iii) Rayleigh laws are valid but a deviation is observed in the very weak fields.
