Since the serious electromagnetic interference due to the widespread application of information technology and wireless communications,there is an increasing demand for the development of novel and ef
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.
