| Popis: | The magnetic phase diagram of Ni1-xZnxCr2O4 demonstrates complex magnetic transitions for x = 0.05 with two long-range magnetic- order transitions at T-C1 = 41K and T-C2 = 17 K. A glasslike feature emerges between TC1 and TC2 with the application of a direct current (dc) magnetic field in alternating current (ac) susceptibility measurements. Dielectric measurements show a change from the conventional dielectric to a quantum-paraelectric-like behavior without anomalies near the magnetic ordering temperature in the range 0.05 |
