Radiofrequency electromagnetic properties the La_0.6Pb_0.4MnO₃manganite under dc-biased magnetization

Abstract

The dc magnetic field and frequency dependences of the transmission coefficient of the four-pole network containing a core made of La 0.6 Pb 0.4 MnO 3 manganite were studied. It is shown that the frequency dispersion of the magnetic permeability of the core material is large at frequencies of about 100 kHz. The factors which influence the value of the transmission coefficient are analysed. Large low-frequency variations of parameters of the four-pole network containing the magnetic circuit made of manganite can be promising for possible device applications.

Magnetic and transport characteristics of oxygenated polycrystalline La0.6Pb0.4MnO3

“…They found, that the magnetoresistance and the maximal Curie temperature were 5.60% (at room temperature in a field of 10 kOe) and 360 K, respectively, for the system with x ¼0.4. There are also few different type of investigations concerning polycrystalline bulk [13][14][15] and single crystalline [16][17][18][19] LPMO materials, thin films [20][21][22][23] and nanograins [24,25] of LPMO.…”
