Abstract The magnetic properties of a mixed spin-2 and spin-1/2 ferromagnetic diamond chain are studied by effective-field theory and Monte Carlo (MC) simulation based on Ising model. The temperature dependences of magnetization, magnetic susceptibility, internal energy, and specific heat are studied, respectively. The exchange interaction dependences of magnetization and the critical temperature are calculated by MC simulation. The changes of magnetization depend on field increasing and then field decreasing under steady-static conditions are also given.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
