چکیده انگلیسی
Magnetic and electrical properties of hexagonal Gd7Rh3 single crystals have been studied by measuring magnetization, magnetic susceptibility, and electrical resistivity. Gd7Rh3 shows antiferromagnetic order below TN=141Â K as reported by Loebich et al; magnetic anisotropy is small in paramagnetic region. Metamagnetic transitions were observed at 4Â K in the external magnetic field up to 130Â kOe along the c-axis and in the c-plane. Electrical resistivity shows a characteristic hump just below TN due to the super-zone gap formation along the new Brillouin zone boundaries. High-temperature resistivity indicates that Gd7Rh3 has a semi-metallic band structure; the band gap energy 4.9Â meV was obtained.
