Estimating the Curie temperature in the Java environment using Monte Carlo simulation: a step-by-step guide from theory to practice

Part One: Introduction to Theory

Curie temperature is an important physical property of magnetic materials. When the temperature exceeds the Curie temperature, the spontaneous magnetization of magnetic materials will disappear. In practical applications, this temperature is critical for the selection and use of magnetic materials. However, how to accurately measure this temperature is a complex problem, especially in theoretical simulations.

Monte Carlo simulation is a method of estimating the behavior of complex systems through random sampling. Its name comes from the famous gambling city - Monte Carlo in Monaco, because it often uses random numbers (just like gambling) for simulations. The main advantage of using the Monte Carlo method to estimate the Curie temperature is that it can handle complex systems without the need to solve complex mathematical equations.

Next, we will see how to estimate the Curie temperature using Monte Carlo simulation in the Java environment.

Code

First, we need to set up a simple Java environment and import the necessary libraries.

import java.util.Random;

public class CurieTemperatureSimulation {
