Magnetokalorický jev v Lu.sub.2./sub.Fe.sub.17./sub. a Y.sub.2./sub.Fe.sub.17./sub. za vysokých hydrostatických tlaků
Součková, Monika ; Kamarád, Jiří ; Arnold, Zdeněk
Magneto-caloric effect of Lu2Fe17 and Y2Fe17 single crystals was measured at ambient pressure and under high hydrostatic pressure up to 1 GPa. Negative magneto-caloric effect was induced by high pressure in both the intermetallics in low-temperature range. Taking into consideration the first-order magnetic transition induced by pressure in Y2Fe17, the results of calculations of magnetic entropy change by Maxwell and by Clausius-Clapeyron equations were compared.
