Magnets for DC motors depend a lot of the application. It is always a balace between technology and price
The steps needed to select properly the type and the shape of magnets that will go into the dc motor can be the following:

Type of the magnet:

Magnetic density and resistance to demagnetization.
The magnets should often supply the highest magnetic strenght to the motor in order to maximize the torque that will be produced.

A strong flux
Finally, the shape of the magnet has to be optimized in order to have the highest magnetic flux going between the rotor and the permanent magnets. A cylinder shape or sector shape is wildely used in this kind of application.
