We report here, temperature dependent Raman spectroscopic measurements on polycrystalline MnV2O4 over the range of 10–300 K. The main aim this study is to investigate spin–phonon correlations across magnetic and structural transition temperatures in system. Temperature magnetization combined with low show existence changes two successive phase transitions. Anomalous line shape parameters some modes are observed during measurements, indicating presence coupling. A significantly high coupling...
In this paper, we report the modulation of structural and magnetic properties with Fe Cr doping at Zn V sites in ZnV2O4. Undoped ZnV2O4 exhibits two anomalies M-T measurements which are assigned to a transition (T S ~ 57 K) followed by N 41 K). With help x-ray diffraction energy dispersive analysis it is found that prepared samples single phase as well stoichiometric. However, both cationic leads disappearance suppression long range ordering cusp like feature below 20 K cusps broaden...
We investigate the effect of Fe and Cr doping at Zn V sites, respectively, on electrical transport behavior polycrystalline spinel ZnV2O4. The resistivity studies as a function temperature reveal presence two different mechanisms: Arrhenius conduction (170-300 K) Mott variable range hopping (VRH) (80-170 K). results also show that sites has pronounced property together with V-V distance, accompanied by decreasing magnetic transition temperature,TN. doping, other hand, shows contrasting...
