magnetism and neutron.

I am going to go to American Physical Society meeting (APS) next March at Denver. I am writing the abstracts of my presentation. I am a kind of exited because I have never been to Denver and I may have chances to talk my study in front of the most appropriate audiences. I am going to give 2 presentations. One is old system about orbital ordered material, the other is also old system about magnetic structural analysis.

I am pretty enjoying study now, two of my projects are close to conclusions. One of the projects, I spent 1 year and almost 9 months to analyze. This system is so complex. And since this system has been studied  extensively around 2000, so many experimental results and theoretical interactions which I have to, of course, be familiar with are published already.

I am thinking about the curiosity. How and where does it come from? As a Scientist, curiosity is one of the most important component (I could not find right word). I want to study harder as much as I can, and I want achievements, promotion, and grants. But I can not work until I am mentally broken. So then hardest working  working harder just before mentally broken state. No. The hardest work as a Scientist should be work hardest not enough to be able to keep abandoned curiosity.

By the way, I have to write something about me. So let me practice here.

I am an experimental physicist studying magnetism. As you know, physics covers wide range of science, such as Space to Particles. But, do you know how we categorize our field? We use “Scale”. Yes, of course you know it, don’t you? The scale is an object defines a set of point for measuring something, such as length, height, temperature, and so on. Our fields are classified the scale of length (more precisely, the scale of distance which interactions matter. ) For example, people studies larger that earth ( > 10^6 m ) I recognize they are studying Space, Also there are physicist studies particle physics studies smaller than ( < 10^-8 m). What I am working on is something like (Sometimes 10^-15) 10-8 m to 10-1 m, it is pretty wide range.

So, I am studying magnetism. Magnetism is a main issue in Physics. For the study of magnetism, basically there are two jobs. One is to know what the magnetic structure looks like, and the other is to know how the magnet becomes magnet. To do these jobs, I use neutron scattering which is produced only by a reactor or positron accelerator. Neutron have been used more than 50 years, still the strongest tool for studying magnetism. Why? It is because that a neutron has no charge and a neutron spin (which is the smallest unit of magnet in the material), which means a neutron has no interaction with electric charge in material but has interaction with spin in material. So we can directly see magnetism in the magnet.

Does it make sense? I have to go today. I would love to write again. I have a lot of things I want to write. Anyway, bye!!
