Ingår i: PHYSICAL REVIEW B. - : AMERICAN PHYSICAL SOC. - 0163-1829. ; 6317:17, s. 4405-
-
Tidskriftsartikel (refereegranskat)abstract
- Dynamic magnetic properties of Y0.7Ca0.3MnO3 are reported. The system appears to attain local ferromagnetic order at T(SRF)approximate to 70 K, where SRF is short-range ferromagnetism. Below this temperature the low-held magnetization becomes history depe

-
Tidskriftsartikel (refereegranskat)abstract
- The magnetic transition temperature, T-c, of Nd0.7Sr0.3Mn1-yMgyO3 decreases with increasing y. In between y = 0.1 and 0.2 the system undergoes a transition from being conducting and ferromagnetic to become insulating and spin glass like. This study is foc

Tidskriftsartikel (refereegranskat)abstract
- Dynamic magnetic properties of the colossal magnetoresistance ferromagnet Ndo(0.7)Sr(0.3)MnO(3) have been explored by ac-susceptibilities and dc-magnetization measurements. The system orders magnetically below T(c)approximate to 235 K with a large differe
