What Are the Characteristics of Au-Fe Spin Glass?

[Rasine]

Hello everyone,

I am an undergratude student doing to research and I am making dirty Au films. At certian concentrations of Fe (say >.5%) this Au-Fe is showing charateristics of a sping glass. I am attempting to learn what exactly a spin glass is and what its trends look like (resistance vs. temp. mainly).

The literature that I have found is eithere too technical or to vague for my understanding. Can anyone suggest intoduction literature or can explain this subject?

Hello,

Au doped with Fe spin glass is a very interesting material and has been widely studied in the field of materials science. A spin glass is a type of magnetic material where the magnetic moments of the atoms are randomly oriented, leading to a disordered and frustrated magnetic state. This results in a complex and unique behavior of the material, which is reflected in its electrical and magnetic properties.

In your research, you have observed the formation of a spin glass in your Au-Fe films when the concentration of Fe is above 0.5%. This is a significant finding and could potentially lead to new applications for this material.

To understand the behavior of spin glasses, it is important to study their temperature-dependent properties, such as resistance. This is because the magnetic moments in a spin glass can be influenced by changes in temperature, leading to changes in its electrical properties. Typically, spin glasses exhibit a gradual decrease in resistance as the temperature is lowered, followed by a sharp drop at a critical temperature, known as the spin glass transition temperature.

I would recommend starting with some introductory literature on spin glasses, such as "Introduction to Spin Glasses" by A.P. Young or "Spin Glasses: A Challenge for Mathematicians" by M. Mézard. These books provide a good overview of the subject and can help you understand the trends in resistance vs. temperature for spin glasses.

I hope this helps in your research and I wish you the best of luck in your studies. Keep exploring and learning about this fascinating material!
