Query: Incorrect equations and information

Unfortunately there aren't many textbooks out there dedicated to the magnetocaloric effect. In fact, this is the only one I've been able to find. This textbook is full of incorrect information from the start. I had to re-derive the basic thermodynamic relations and Maxwell equations in Chapter 2 in order to correct the more complex equations used later in the book. Much of the explanations are confusing, unclear, contradictory, if not outright wrong.I really wish the authors would make a serious revision, or that other experts in the field would publish a better book with more accurate information.
