CCP on Computational Magnetism

CCP-mag是一个新提出的合作计算项目，汇集了英国磁学领域的研究人员。磁现象在技术上高度相关，并且具有应用范围，从计算机中的磁存储，超过风力发电机中使用的强永磁体，到磁冷却装置，其可以通过更节能的装置或磁传感器来取代当前的冰箱。需要同时了解磁性的不同方面，从微观开始，量子力学现象，首先引起磁性，电磁学的几何效应，这是相关的更大的长度尺度。英国已经有非常强大的团队，致力于磁性的不同方面，并使用不同的技术来研究磁性现象。这个CCP-MAG网络的主要重点是磁性材料的多尺度描述，以及实验学家用来分析和解释测量结果的方法和代码。其目的是将现有的专门知识联合收割机结合起来，使各小组能够在不同的尺度上同时处理复杂的现象。为此，我们将接口现有的代码，使他们能够以一种简单的方式交换数据，以提供新的计算方式，这在以前是非常困难的。

CCP-mag is a newly proposed Collaborative Computational Project, which brings together UK researchers in the field of magnetism. Magnetic phenomena are technologically highly relevant, and have applications, ranging from magnetic storage in computers, over strong permanent magnets, as used in wind driven generators, to magnetic cooling devices, which could replace current refrigerators by more energy efficient ones, or magnetic sensors.A full understanding of these complex phenomena, which could lead to the development of novel materials, requires a simultaneous understanding of different aspects of magnetism, starting from the microscopic, quantum mechanic phenomena, giving rise to magnetism in the first place, to geometrical effects of electromagnetism, which are relevant at larger length scales. The UK already has very strong groups, working on different facets of magnetism and using different techniques to study magnetic phenomena.The main emphasis of this CCP-mag network is on a multi-scale description of magnetic materials, and on methods and codes used by experimentalists to analyse and interpret their measurements. The aim is to combine the present expertise, and bring the groups together to tackle the complex phenomena simultaneously on different length scales. To this end, we will interface the existing codes, such that they can exchange data in an easy way, to provide new ways of calculations, which previously would be very difficult to perform.
