Structural anomalies at the magnetic transition in centrosymmetricBiMnO3

The Effect of Transition Metals Incorporation on the Structural and Magnetic Properties of Magnesium Oxide Nanoparticles

Pure and doped magnesium oxide nanoparticles were successfully synthesized employing a sol-gel process. The synthesized nanoparticles were characterized by thermal differential analysis, X-ray powder diffraction, transmission electron microscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometer. X-ray diffraction patterns confirmed the crysta...

THERMAL EXPANSION ANOMALIES AT THE MAGNETIC TRANSITION OF Mn3Ga1-xAlxC (x 0.05)

The temperature variations of the lattice parameter of the pseudoternary compounds Mn3Gal-,Al,C (x j 0.05) were measured by using of powder X-ray diffraction. The anomalies which correspond to the magnetic phase transitions were observed in the thermal expansion curves. The intermetallic compound MnaGaC is an ordered cubic crystal of a perovskite type structure. The magnetic properties are char...

asset pricing anomalies at the firm level

Anomaly is deviation from common rules and in finance it can be defined as a pattern in the average of stock return that is not consistent with the prevailing asset pricing models literature. For anomaly investigation two common methods are used: portfolio approach and individual firm approach. This paper wants to shed light on anomalies of capital asset pricing model at the individual firm lev...

Pigeons at Magnetic Anomalies: the Effects of Loft Location

Homing pigeons from our old lofts at Fox Ridge Farm in Lincoln, MA, were disoriented when released at places where the earth's magnetic field was irregular so-called 'magnetic anomalies'. The orientation of pigeons raised in our lofts at Cornell in Ithaca, NY, was unaffected by anomalies. Further experiments in Lincoln showed that sibling pigeons raised and trained to lofts only 2.5 km apart be...
