Significant suppression of ferromagnetism by hydrostatic pressure in the diluted magnetic semiconductor Sb2-xVxTe3
Original language description
The paper reports on the hydrostatic pressure dependence of the magnetotransport properties of ferromagnetic Sb2-xVxTe3 single crystals with x = 0.02 ? 0.03. Pressure significantly increases the free hole concentration in these compounds. In turn, the Curie temperature is suppressed by roughly 40%, which goes against many models that would predict an increase in Curie temperature? with increasing carrier concentration. These results indicate that the ferromagnetism in these materials is carrier-mediated, and that a full RKKY model that takes into account the oscillatory nature of the indirect exchange interaction among localized spins is needed in order to explain the data.

Czech description
Článek se zabývá vlivem hydrostatického tlaku na magnetotransportní vlastnosti monokrystalů Sb2-xVxTe3. Výsledky naznačují, že ferromagnetismus je v těchto materiálech skutečně zprostředkován volnými děrami v rámci RKKY teorie.
