(a) M–T curves along the c axis at different magnetic fields from 0.01 to 5 T. (b) M–H curves along the c axis at different temperatures from 215 to 380 K. (c) M–T curves along the a axis at different magnetic fields from 0.01 to 2 T. (d) M–H curves along the a axis at different temperatures from 385 to 397 K. The insets in (b) and (d) show the linear temperature dependence of TSR2 along the c and a axes, respectively. |
