The normal way to do this would be to separate each mat-step out into its own formgroup.

HTML

<mat-step [stepControl]="myForm1">
  <form [formGroup]="myForm1">
    <mat-form-field ....
  </form>
</mat-step>
<mat-step [stepControl]="myForm2">
  <form [formGroup]="myForm2">
    <mat-form-field ....
  </form>
</mat-step>
<mat-step [stepControl]="myForm3">
  <form [formGroup]="myForm3">
    <mat-form-field ....
  </form>
</mat-step>

and if every form group have more than one field .. how can i get the data the user inputted ?

These are just standard form groups. You'd get them in the same way you'd get from a form group if it was a single control with multiple fields. There's nothing special about this.
