How do I get ode45 to output the dependent variable value at each time step? I have other material properties in my differential equation that change with temperature, so I must update them with each change in temperature.

the equation looks like this:
dT/dt = T/cB(T,B) * d/dT( M(T)) * d/dt( B(t))
cB(T) = the specific heat M(T) = the magnetization of the material

The answer to your topic is that the odefun, i.e. the function you pass to ode45 as in ode45(odefun,tspan,x0) needs include the line
y
as in
function dydt = odefun(t,y)
%[...] code
y
but I don't think that's what you really want to do/know. Could you detail your question? Also, what is B(t), is that another state you're not telling us about, or is that a known function/input?
Is there a closed form of M(T), cB(T,B) that you are using, or is it a look-up table?
