Using neutron scattering to understand magnetism
In this post, I aim to provide some qualitative understanding of some of the ways we can use neutrons to understand magnetism. Neutrons are a powerful probe of condensed matter allowing us to

Introduction to Machine Learning
Machine Learning In order to learn something, you have to make a series of assumptions about the problem at hand. We make decision based on a set of beliefs and machine learning (ML) tries to place a

Isolated Magnetic Charges - The Search for Magnetic Monopoles
We all learned about isolated electric charges in high school. These are the reason why balloons stick to walls after rubbing them on a course surface such as your jumper - the electric charges are manipulated

Frustration in magnetism
Think about spins coupled antiferromagnetically on a triangle lattice. Consider the lower two vertices - if the spins on these sites are arranged with one 'up' and one 'down' then we minimise the energy,

Magnetic monopoles in spin ice
Spin ice is the name given to a class of magnetic materials that have a property called frustration, which occurs due to the lattice geometry - the way the atoms are arranged inside the crystal. These

diffraction: structure factor
each type of lattice has a condition associated with it that describes positive interference during scattering. this is encapsulated within the so-called structure factor and explains the systematic absenses

diffraction patterns
we can look inside crystals using x-rays and neutrons. in the simplest case of elastic scattering, the incoming and outgoing wavevectors have the same magnitude, that is |k| = 2 π /λ . here,
