Figure 6
Magnetic transition behavior of the Co6 alloy. (a) Representative isothermal magnetization M-H loops under magnetic fields up to 5.0 T. (b) dM/dH curve measured at a temperature of 309 K showing two inflection points that indicate the occurrence of two successive magnetostructural transformations. (c) The temperature dependent hysteresis loss (HL) plot during the isothermal magnetization M-H cycling. The fitting line just acts as a guide for the eye. (d) Arrott (M2 vs H/M) plots revealing the appearance of the magnetic-field-induced austenite (MIA) at temperatures above 295 K.
