In recent years,considerable attention has been paid to the soft and hard magnetic nano-composite systems due to their charming application foreground on improvement in the magnetic properties.For the
Metal-organic frameworks (MOFs) may exhibit a variety of interesting physical and chemical properties.Here we demonstrate the magnetoelectric (ME) coupling in a metal-organic framework [(CH3)2NH2]Mn(H
Combining the highly spatial-resolved topographic imaging with the optical excitation and spectral analysis,photo-assisted STM has provided a unique tool to study optically excited vibration and elect
The tip expansion due to laser illumination is an important issue for the development of laser-assisted scanning tunneling microscope (STM).In this letter,the thermal expansion of an STM tip induced b
Current information technology includes information procession and information storage which are carried out by charge-based devices and magnetic material respectively.To efficient manipulate the orie
Ferromagnetic semiconductor (Ga,Mn)As has attracted great attention for both fundamental physics and potential applications since its discovery in 1990s[1].Most attractive properties of (Ga,Mn)As resu
稀土正铁氧体HoFeO3具有Fe3+ 和Ho3+ 两套磁性子晶格,因此展现出丰富的磁性质.已有的研究表明:在T<647 K以下,Fe3+发生反铁磁有序,反铁磁轴沿a方向,c方向具有弱的铁磁分量;51 K<T<62 K,Fe3+发生自旋变向,反铁磁轴由a方向逐渐变到c方向;T<51 K,反铁磁轴沿c方向;当T<4.5 K时,Ho3+发生反铁磁有序.
High quality Co doped ZnO thin films are grown on single crystalline AL2O3 (0001) by oxygen plasma assisted molecular beam epitaxy.Micro-Raman measurements were performed to study the influence of Co
