The oxygen isotope effect of the ferromagnetic transition in itinerant ferromagnet strontium ruthenate SrRuO3 with a Curie temperature Tc of 160 K is studied. We observed for the first time a shift of ∆Tc ~ 1 K by oxygen isotope substitution of 16O

Recently, we have developed new methods to form nano-structures consisting of small magnetic domains of 5–20 nm with random orientations, when some ferromagnetic materials are exposed to the magnetic field with microwave frequencies. To investigate

We have studied transport and magnetic properties of (LaSr)Co 1− x Fe x O 4 system. The conduction of (LaSr)CoO 4 is three-dimensional variable range hopping at low temperatures below ∼300 K and is expected to be thermally activated hopping above

We have performed the powder neutron diffraction measurements on the solid solutions of SrRu_{1-x}Mn_xO_3, and found that the itinerant ferromagnetic order observed in pure SrRuO_3 changes into the C-type antiferromagnetic (AF) order with nearly loca

57 Fe Mossbauer spectroscopic studies were carried out on the single layered perovskite, LaSrFeO 4 , in the temperature range 15–380 K. The observed line width asymmetries in the line shapes of the spectra were understood to arise from a chemical d

Electron-doped metallic states of Ca1−x Y x VO3 and Ca1−x Y x TiO3 change into non-metallic states around x∼0.4 and 0.6, respectively. The residual resistivity in the metallic states increases with increasing effective magnetic moment or coeffi
