Paramagnetic Meissner effect in YBa2Cu3O7: influence of AC magnetic field and magnetic relaxation
Result description
We have investigated the superconducting transition region in YBa2Cu3O7 single crystal showing the paramagnetic Meissner effect (PME). In the temperature region where the PME appears the sample reveals logarithmic relaxation of magnetization. The decay rate appreciably depends on the direction of the magnetic field fields. This phenomenon indicates that the PME may by caused by thermal fluctuations

Paramagnetický Meissnerův jev v YBa2Cu3O7: vliv střídavého pole a magnetické relaxace
Czech description
Zkoumali jsme oblast supravodivého přechodu v monokrystalu YBa2Cu3O7, ve kterém dochází k paramagnetickému Meisnerovu (PMJ). V oblasti teplot, kde PMJ vzniká, magnetizace logaritmicky relaxuje. Rychlost relaxace závisí na směru magnetického pole. To ukazuje, že PMJ může souviset s tepelnými fluktuacemi
