The coexistence of multiple ferroic orders, i.e. multiferroicity, is a scarce property to be found in materials. Historically, this state has been found mainly in 3-dimensional complex oxides, but so far this state has still been elusive for the most

Effect of UV radiation on the structure of graphene oxide in water and its impact on cytotoxicity and As(III) adsorption

Autor: Gallegos-Perez, W. R., Reynosa-Martinez, A. C., Soto-Ortiz, C., Alvarez-Lemus, M. A., Barroso-Flores, J., Montalvo, V. Garcia, Lopez-Honorato, E.

Graphene oxide (GO) is widely used in different applications, however once release into the environment it can change its structure and affect the transport of important contaminants such as arsenic. In this work we show that UV radiation, even in th

Phonons correlation with magnetic excitations in weak ferromagnet YCrO3

Autor: Sharma, Yogesh, Sahoo, Satyaprakash, Perez, W., Katiyar, Ram S.

We report on the temperature dependent Raman spectroscopic studies of orthorombic distorted perovskite YCrO3 in the temperature range of 20-300K. Temperature dependence of DC-magnetization measurement under field cooled and zero field cooled modes co
