Strong microwave absorption observed in dielectric La1.5Sr0.5NiO4 nanoparticles
P. T. Tho, C. T. A. Xuan, D. M. Quang +5
LaSrNiO is well known to have a colossal dielectric constant (). The LaSrNiO nanoparticle powder was prepared by a combi…
Interacting Superparamagnetism in La0.7Sr0.3MnO3 Nanoparticles
Ha M. Nguyen, D. H. Manh, L. V. Hong +2
The magnetic order of La0.7Sr0.3MnO3 nanoparticles (NPs) fabricated in a SPEX D8000 mill was systematically studied. The La0.7Sr0.3MnO3 nanocrystals grow from the milled constituen…
Effects of dilution on magnetic and transport properties of La0.7Ca0.3Mn1-xM'xO3
D. N. H. Nam, H. S. Hong, N. V. Khien +5
Magnetic and transport properties of La0.7Ca0.3Mn1-xM'xO3 (M'=Al,Ti) are studied. The dilution of the Mn lattice results in a weakening of the ferromagnetism, a deterioration of th…
Temperature memory and resistive glassy behaviors of a perovskite manganite
D. N. H. Nam, N. V. Khien, N. V. Dai +2
This paper reports the observations of long-time relaxation, aging, and temperature memory behaviors of resistance and magnetization in the ferromagnetic state of a polycrystalline…
Impact of in-plane currents on magnetoresistance properties of an exchange-biased spin-valve with insulating antiferromagnetic layer
D. N. H. Nam, N. C. Thuan, L. V. Hong +4
The impact of in-plane alternating currents on the exchange bias, resistance, and magnetoresistance of a CoFe/NiCoO/CoFe/Cu/CoFe spin-valve is studied. With increasing current, the…
Room-temperature magnetocaloric effect in La0.7Sr0.3Mn1-xM'xO3 (M'=Al, Ti)
D. N. H. Nam, N. V. Dai, L. V. Hong +4
Magnetic entropy and adiabatic temperature changes in and above the room-temperature region has been measured for La0.7Sr0.3Mn1-xM'xO3 (M' = Al, Ti) by means of magnetization and h…
