The magnetization of Y(Co/sub 1-x/Al/sub x/) intermetallides is studied for strong pulsed magnetic fields or =0.075 at a field whose strength decreases as x increases. The band model for d-electron metamagnetism is used to interpret the results. The metamagnetic transition field 660 kOe and the magnetic moment 1.4 /sub B// (formula unit) which characterize the magnetization curve for YCo2 are found by extrapolating to x = 0. The results are compared with data for other RCo2 compounds for which the cobalt subsystem has similar properties.read more

First- and second-order magnetic phase transitions in (R-Y)Co2 and R(Co-Al)2 (R=heavy rare-earth element) compounds
TL;DR: In this paper, the types of magnetic phase transitions in (R-Y)Co2 and RCo2 (R=heavy rare-earth element) under high pressure are studied by making use of a phenomenological model where the coexistence of localised moments on R atoms and itinerant d electrons is assumed.
