The most important latest scientific results
- The exchange shift of the hysteresis magnetization loop of was revealed in Nd2/3Ca1/3MnO3 manganite, which is characterized by a colossal magnetoresistance. This result confirmed the existence of magnetic phase separation and demonstrated the presence of an exchange interaction between ferromagnetic nanoclusters and an antiferromagnetic matrix in manganites (2014).
- For the first time, by electronic spin resonance (ESR), SQUID magnetometry and electric resistance measurements a direct evidence of the fact that below the charge ordering temperature, Tco ~ 212 K, the compound is a mixture of charge-ordered and charge-disordered phases, which is self-organizing in the process of phase transformation into charge-ordered state was obtained. (2016).
- For the first time, a high-temperature anomaly of the magnetic properties of Co-containing double layered hydroxides [Со2+1-xAl3+x(OH)2]x+(CO3y-)x/y·5H2O was detected in the temperature range 75 – 175 K; iwas established that the anomaly is due to the effect of "freezing" of hydrogen bonds (2017).
- For the first time the exchange shift of the hysteresis loops was discovered in a new promising multiferoid BiFe0.5Sc0.5O3, which was recently synthesized under high pressure conditions that occurs when cooled in a magnetic field below the magnetic ordering temperature and indicates the magnetic phase separation of this compound in a magnetically ordered state (2018).
