Hyperfine interactions, magnetic, transport and structural properties of La0.67Ca0.33Mn0.9457Fe0.06O3

Original Kurzfassung:
The La0.67Ca0.33Mn0.9457Fe0.06O3 compound was studied using powder X-ray diffraction, VSM magnetometry,four-probe resistance measurements and 57Fe Mössbauer spectroscopy. The Mössbauer measurements were performed between 15 K and 850 K and showed good agreement between Curie temperature
determined from temperature dependences of the hyperfine field (141 K) and DC magnetization (142 K). They show the inhomogeneous character of the magnetic transition and the coexistence of ferromagnetic and paramagnetic phases in the temperature range 110 K ≤ T < 141 K. Our results confirmed that substitution of Fe3+ for Mn3+ strongly affects the magnetic and transport properties of the parent compound.
It causes a difference between Curie temperature and the metal-insulator transition temperature of about 80 K and a strong reduction of their values. X-ray diffraction measurements were performed between 4 and 500 K and showed complete suppression of the thermal expansion anomaly at Curie temperature.
